Influence of oral processing on appetite and food intake – A systematic review and meta-analysis

While slow and prolonged food consumption is believed to make you feel more full, this 2018 review assessed the impact of oral processing characteristics (for example chewing and lubrication) on food intake and measures of appetite such as hunger and desire to eat. The systematic literature search on 6 different databases yielded 38 papers (detailing 40 unique studies with 70 subgroups), which were used for meta-analysis. Raw data on food intake was seen 65 times, hunger 22 times, and desire to eat ratings 15 times. Oral processing parameters such as number of chews, eating rate and texture manipulation seemed to substantially affect food consumption and appetite ratings to a lesser extent. Meta-analysis also indicated that aspects of oral processing related to chewing elicited a significant effect on self-reported hunger and food intake. Krop et al. (2020) insist that future research should confirm the role of oral processing including chewing and lubrication in promoting satiety, especially since few studies have reported the impact of lubrication on appetite.

Perceptual salience influences food choices independently of health and taste preferences

Dai et al. (2020) planned to determine the role of visual attention in healthy eating intentions and choices since it was not yet fully understood how people decide what to eat. Two-alternative forced choice tests were conducted to make participants choose 2 pairs of healthy and unhealthy foods, varying in taste preference. The researchers modified […]

Building a neuroscience of pleasure and well-being

While hedonic pleasure has been linked with brain function in the past, Berridge & Kringelbach (2011) explore new insights into how brains contribute to the hedonic aspect of sustained or frequent pleasure. Well-being and happiness have been reported to require both positive affect or pleasure (hedonia) and a sense of meaningfulness or engagement in life. […]
